I have used Eotechs on my AR's for a good while with good results, but would like to try something different. Either an Aimpoint with a magnifier, or an ACOG. I am assuming that the fiber optic tube on the ACOG is a non-issue as far as durability. Mostly I like the idea of battery life. While I have had good results and no complaints with the various Eotechs, what struck me about an Aimpoint was how naturally the eye looks through it and how no-brainer the "dot" is. What strikes me about the ACOG is that folks who use them swear by them (like everything else, but perhaps more so?).

Bad times, they are coming.

In the meantime, I'll continue to tinker with my No. 1's ... the opposite end of the spectrum, but still quite effective.
